Sensors may include accelerometers, gyroscopes, thermometers, hydrometers, pH, electrolyte (e.g., potassium, sodium, etc.) sensors, and the like. These and other sensors may be configured to measure different physiological data of the athlete, including impact, body temperature, hydration, illness, heart rate, and the like. In some embodiments, sensors on the mouthguard are integrated with external sensors (e.g., accelerometers on a helmet, chest-worn heart rate monitor) on the athlete to provide additional or more accurate physiological data.

Description

CROSS REFERENCE TO RELATED APPLICATION
• This application claims the benefit of U.S. Provisional Application No. 62/736,015 titled “Device for Athlete Physiology Monitoring,” filed Sep. 25, 2018 by the inventors herein, which application is incorporated herein by reference in its entirety.
FIELD OF THE INVENTION
• The present invention relates generally to systems and methods for monitoring physiological conditions of athletes during athletic events, and more particularly to a system including at least a mouthguard equipped with one or more sensors and processors configured for real-time monitoring of a physiological data of an athlete.
BACKGROUND
• Athletes of all types face risk of injury during practice, training, and competition. For example, professional football players frequently suffer injuries including fractures, sprains, and more dangerous head injuries, such as concussions. Throughout a sporting event, a player may experience a significant impact that jars their head on multiple occasions, creating a cumulative effect that exacerbates a brain injury, possible leading to a concussion or even more serious injury. Similarly, athletes can also be subject to the insidious effects of heat exhaustion and heatstroke. Again, similar to concussions, heatstroke and heat exhaustion are the results on the body due to cumulative exposure to high temperatures and can sometimes go undetected until the athlete is in an emergency situation. However, in the midst of competition, players, coaches, and other team staff may pay limited attention to the building risk of serious injury, leaving the athlete exposed to risk of serious and long-term injury.
• It would therefore be advantageous to provide a system and method capable of monitoring the physiological conditions of an athlete in real-time during an athletic event, such that if they experience conditions that present significant risk to their health, team staff may intervene to take them off the field, give them an appropriate rest period, and if necessary seek immediate medical intervention to mitigate the risk of any injury progressing.
SUMMARY OF THE INVENTION
• Disclosed herein is a system and method for capturing various physiological data associated with an athlete in real-time during an athletic event to detect the occurrence of a condition that risks the player's health, which system and method employ an athlete monitoring unit including at least a smart, physiology-monitoring mouthguard (SPMM) device. In certain configurations, the athlete monitoring unit is configured to provide real-time and/or recorded physiological data of an athlete to a user. The athlete monitoring unit may be configured to record physiological data for later retrieval. The athlete monitoring unit may further be configured as a compliant and/or moldable mouthguard, which is generally a convenient form factor for athletes and other users. The athlete monitoring unit may be configured to measure multiple physiologic parameters of an athlete. In certain configurations, each parameter is measured sequentially, while in other configurations, some parameters are measured simultaneously.
• In an exemplary embodiment, a system is provided including a mouthguard having a substrate, a computing or data-acquisition platform, sensors, a device-side user interface, a monitoring-side user interface, a communication system, a data storage module, a power module, and software for data and/or signal processing. Some configurations may only include electronic systems on the athlete monitoring unit, such as a substrate, sensors, a power module, and a communication system and/or data storage module. Other configurations may only include electronic systems configured to operate with a mouthguard, such as by attaching sensors, a power module, and a communication system and/or data storage module to a typical mouthguard. Furthermore, electronic systems can include a printed circuit that is directly formed on or into the mouthguard substrate. Thus, the athlete monitoring unit and system can be configured to accommodate many cost and functional requirements.
• In accordance with certain aspects of an exemplary embodiment, a system for monitoring the physiological condition of an athlete is provided, comprising: at least one athlete monitoring unit comprising a mouthguard, at least one sensor attached to the mouthguard, wherein the sensor is configured to sense a physiological condition of an athlete on which the athlete monitoring unit is worn, and a microcontroller in data communication with the at least one sensor; and a base station having a processor and a data memory, wherein the base station is in data communication with the athlete monitoring unit, the base station having computer executable code stored thereon configured to receive physiological data from the athlete monitoring unit, compare the physiological data received from the athlete monitoring unit with a preset threshold value for the physiological data, and upon a determination at the base station that the physiological data received from the athlete monitoring unit exceeds the threshold value, generate at the base station a human-discernable alert.
• In accordance with further aspects of an exemplary embodiment, a method for monitoring athlete physiological data is provided, comprising: providing at least one athlete monitoring unit comprising a mouthguard, at least one sensor attached to the mouthguard, wherein the sensor is configured to sense a physiological condition of an athlete on which the athlete monitoring unit is worn, and a microcontroller in data communication with the at least one sensor; and providing a base station having a processor and a data memory, wherein the base station is in data communication with the athlete monitoring unit; receiving at the base station physiological data from the athlete monitoring unit; comparing at the base station the physiological data received from the athlete monitoring unit with a preset threshold value for the physiological data; and upon a determination at the base station that the physiological data received from the athlete monitoring unit exceeds the threshold value, generating at the base station a human-discernable alert.

• Provided herein is a system and method for capturing various physiological data associated with an athlete in real-time during an athletic event to detect the occurrence of a condition that risks the player's health, which system and method employ a smart, physiology-monitoring mouthguard (SPMM) device. With particular reference toFIG. 1 and in accordance with certain aspects of an exemplary embodiment,system100 includes at least oneathlete monitoring unit110 including amouthguard120 that conforms to an athlete's mouth, and more particularly their upper teeth. Mouthguard120 includes at least one mouthguard-mountedsensor122, and optionally a plurality of mouthguard-mountedsensors122, for detecting physiological conditions experienced by the athlete during an athletic event. In accordance with certain aspects of an embodiment,athlete monitoring unit110 may include multiple integrated sensors, including both mouthguard-mountedsensors122 and other body-worn sensors130, as discussed in greater detail below, that may be customized or selected for each athlete. In certain configurations,athlete monitoring unit110 includes amicrocontroller140 that is in data communication withsensors122 and130. WhileFIG. 1 showsmicrocontroller140 positioned remotely frommouthguard120,microcontroller140 may in certain configurations be integrated withinmouthguard120.Microcontroller140 may receive signals (e.g., signals indicative of physiological conditions experienced by the athlete) fromsensors122 and130, and may control each such sensor's operation (e.g., turn each sensor on and/or off).
• In an exemplary embodiment, thesensors122 and130 are multiplexed tomicrocontroller140 using, by way of non-limiting example, BLUETOOTH® connectivity, although other wireless or wired communication protocols may likewise be employed as will be apparent to those of ordinary skill in the art.Microcontroller140 is likewise preferably in data communication with abase station160 through acommunication module142 ofathlete monitoring unit110.Microcontroller140 is preferably configured to process physiological data and signals, and to transmit such data and signals tobase station160.Microcontroller140 is preferably configured to store data in adata storage module144, transmit such data tobase station160, and/or delete physiological data fromdata storage module144, as described in further detail below. Likewise,base station160 is preferably configured to employ command and control functions (e.g.,system100 set-up or initialization), perform real-time data collection and routing, perform real-time physiology monitoring and alerting, provide a graphical user interface, and perform any desired post-processing of data received fromathlete monitoring unit110.
• Preferably,athlete monitoring unit110 also includes apower module146, such as a rechargeable battery, for powering the components ofathlete monitoring unit110.
• In certain configurations,microcontroller140 directly communicates withbase station160, while inother configurations microcontroller140 indirectly communicates withbase station160. Such communications may be wireless or wired communications. For example,microcontroller140 may wirelessly communicate withbase station160 using a BLUETOOTH® connection (or radio, Wi-Fi, or other wireless connection) employed bycommunication module142 in accordance with well-known wireless communication protocols and infrastructure, to transmit physiological data fromathlete monitoring unit110 tobase station160. As a further example,microcontroller140 may communicate with anintermediate communication module150 that further communicates withbase station160.Intermediate communication module150 may, by way of non-limiting example, be a body- or equipment-worn repeater module having a higher power transmitter module and more power capacity (e.g., an additional battery) that can communicate physiological data tobase station160 under a variety of challenging communication environments (e.g., poor signal quality due to noise, relative locations ofmicrocontrollers140,intermediate modules150 and/orbase stations160, interference, weather, etc.). Alternatively or additionally,intermediate communication modules150 may be positioned on an athletic field or other area surrounding the athletes at optimal positions between the athletes andbase station160. Thus,microcontroller140 may comprise a low-power microcontroller configured to increase the efficiency and reduce the power requirements ofathlete monitoring unit110.
• In certain configurations, more than oneintermediate communication module150 may be provided that communicate betweenathlete monitoring unit110 andbase station160. In other configurations, eachintermediate communication module150 and/ormicrocontroller140 may only communicate with predetermined intermediate communication modules and/orbase stations150. In still other configurations, eachintermediate communication module150 and/ormicrocontroller140 may communicate with a variable set ofintermediate communication modules150 and/orbase stations160 depending upon a variety of factors (e.g., signal quality due to noise, relative locations ofmicrocontrollers140,intermediate communication modules150, and/orbase stations160, interference, weather, etc.). By way of non-limiting example, eachmicrocontroller140 and/orintermediate communication module150 may communicate withintermediate communication modules150 that are spatially close to the athlete'sathlete monitoring unit110 at particular moments.
• In other configurations,system100 many includemultiple base stations160. In some configurations,base station160 may comprise a smartphone or tablet device, while in otherconfigurations base station160 may comprise a desktop computer, laptop, receiver, or the like.Base station160 may be configured to record and display incoming data. In another configuration,base station160 may be configured to activate alerts when triggered by particular physiological data or conditions. For example, for a device measuring physiological data including high acceleration (high-G-force) or impacts to an athlete (e.g., from anathlete monitoring unit110 having asensor122 and/or130 for measuring acceleration such as an accelerometer or gyroscope, as further described below), abase station160 may be configured to issue an alert when the athlete experiences a certain number of occurrences within a predetermined duration (e.g., a single sporting event). The alert may indicate a change of the athlete's status, for example, from “unmarked” to “in-danger,” such that coaches, health professionals, authorities, etc. can intervene as necessary. Other configurations of the system can include similar algorithms for other sensors (as further described below).
• In one configuration, thesystem100 monitors for concussions of an athlete. For example, thesystem100 monitors for concussions by measuring impact forces via acceleration measurements.Athlete monitoring unit110 may include a three-axis accelerometer to measure acceleration, which can be recorded directly indata storage module144, which may comprise (by way of non-limiting example) a non-volatile memory. In other configurations, data can be streamed or transmitted toremote base station160, which may comprise (by way of non-limiting example) an off-field central team data collection system (as described above; see also Table 2, below). In still other configurations, the acceleration data can be simultaneously streamed or transmitted tobase station160 and recorded in a storage module atbase station160.
• In an exemplary embodiment, acceleration data is only recorded or streamed when the accelerometer(s) ofathlete monitoring unit110 measure an impact force exceeding a pre-set threshold (on-demand operation), such as an impact event. For example, data may only be recorded or streamed for a collection interval after an impact event. The collection interval for each impact event can last from several seconds preceding the event and throughout the event, to a time after the event. For example, the collection interval may be 1 second before the event and 5 seconds after the event, and in another example, the collection interval may be 2 seconds before the impact event and 10 seconds after the impact event. The system may readily be adapted to provide for longer or shorter data collection durations as may be deemed appropriate for a particular athletic event. Each occurrence of an impact event may be time-stamped, processed, or synced at one of thebase stations160. Thus, operating on-demand may reduce power consumption of the device and increase battery life of the device.
• In an exemplary embodiment, the substrate ofmouthguard120 is similar to a typical mouthguard, such as those used during athletic activities (e.g., football). Some mouthguards include an attachment strap that is configured to couple to a helmet or jersey. Thus, some configurations herein may include wiring that is integrated with an attachment strap attaching mouthguard120 to the athlete's helmet, jersey, pads, or other equipment for power module and/or communication systems further integrated with the athlete's helmet, jersey, pads, or other equipment (such as described below). In another configuration, the mouthguard may be custom designed for a particular athlete, and in yet another configuration the mouthguard may be custom designed to house electronic systems of the device-side platform (such as the microcontroller, sensors, etc.) to protect the electronic systems while allowing sufficient measurement of physiological data and safety of the athlete. Themouthguard120 may be manufactured according to typical methods, such as injection molding, additive manufacturing, and the like.
• In accordance with certain features of an exemplary embodiment,sensors122 and130 may be configured to measure physiological data of the athlete. Thesensors122 and130 are configured to sufficiently and reliably provide signals for monitoring the health of the athlete. Different types ofsensors122 and130 may be chosen based on the anticipated activity or sport, the health and age of the athlete, and size and power requirements of thesystem100. For example, thesensors122 and130 may include accelerometers (e.g., multiple three-axis accelerometers, as discussed above), gyroscopes, thermometers, hydrometers, pH sensors, electrolyte (e.g., potassium, sodium, etc.) sensors, heart rate monitors, and the like, the construction of which are known to those skilled in the art. These and other sensors may be configured to measure different physiological data of the athlete, including impact, body temperature, hydration, illness, heart rate, and the like. In some configurations,sensors122 on themouthguard120 are integrated withexternal sensors130 on the athlete to provide additional or more accurate physiological data. For example, physiological data from accelerometers on themouthguard120 can be integrated with physiological data from accelerometers on the athlete's helmet (e.g., via the microcontroller140) to more accurately determine impact forces relative to the head. As a further example, physiological data from themouthguard120 can be integrated with physiological data from heart rate monitors or temperature sensors on the athlete (e.g., on the athlete's body, jersey, pads, helmet, or the like, via the microcontroller140) to more accurately determine the athlete's temperature or overall health. Somesensors122 and130 may be monitored continuously, whileother sensors122 and130 may be monitored discretely or intermittently.
• In an exemplary embodiment,system100 includes at least onebase station160, as discussed above. Base station160 (or, computing/data-acquisition platform or monitoring-side platform) is preferably configured to receive all of the physiological data transmitted from theathlete monitoring unit110.Base station160 may be further configured to process the received physiological data, such as according to a set of pre-defined rules or algorithms. Furthermore,base station160 may be configured to issue alerts, such as determined by the rules or algorithms regarding the status of the athlete (e.g., “unmarked,” “in danger”, or the like). Still further, some configurations ofbase station160 may display the physiological data, along with any alerts, or cause other devices (e.g., smartphone of a healthcare provider) to display alerts or physiological data.FIG. 2 is an exemplary view of a display screen from a user interface ofbase station160, which may (by way of non-limiting example) provide for eachsensor122 and130 of each athlete monitoring unit110 a display of data (e.g., numeric values, graphs, or other indicia as may be appropriate for the sensed physiological condition) associated with each sensor, along with an “Alerts”indicator210 associated with eachathlete monitoring unit100 to provide a quickly identifiable indicia of an overall physiological condition of the athlete (e.g., distinct color indicators to indicate unmarked, in danger, and the like). By way of non-limiting example,base station160 may comprise a smartphone (e.g., an Android®- or iOS®-based phone or tablet), a personal PC or laptop, or the like. Still further, eachbase station160 may be configured to receive physiological data from and operate manyathlete monitoring units110 at a particular time.
• In an exemplary embodiment,system100 may have adjustable settings of the electronics on theathlete monitoring unit110. For example, the system may include a device-side user interface (UI)170, such as a graphical user interface, in data communication withathlete monitoring unit110. The device-side UI170 may be configured to adjust a selection of many settings, such as change data signal sensitivity, trigger thresholds, device initialization (e.g., how to turn on eachathlete monitoring unit110 or start data monitoring/acquisition), setup parameters, establishing a unique identification (an identifiable tag, e.g., a radiofrequency or bar code tag) for each athlete monitoring unit per athlete, and the like. In an exemplary embodiment, the device-side UI170 operates on a PC or laptop (although other embodiments operate on a smartphone, tablet, or the like), which transmits settings to theathlete monitoring unit110. WhileFIG. 1 showsdevice side UI170 implemented on a computing device that is separate frombase station160,device side UI170 may alternatively be operated as an executable software module onbase station160 without departing from the spirit and scope of the invention.
• In an exemplary embodiment, thesystem100 may also have adjustable settings of the base station160 (monitoring-side). For example, thesystem100 may include a monitoringside user interface162, such as a graphical user interface, on the base station160 (as depicted inFIG. 2). The monitoring-side UI162 may be configured to receive, process, and transmit physiological data, initialize other components (e.g., individualathlete monitoring units110,intermediate modules150,other base stations160, etc.), start and/or stop data monitoring or acquisition, raise data-dependent alerts, maintain time-base forathlete monitoring units110, monitor battery levels, initiate communications with healthcare providers, register individual athlete monitoring units110 (e.g., using RFID), and the like.
• In an exemplary embodiment, the communications system comprises a BLUETOOTH® low-energy (BLE) system. For example, typical BLE systems have approximate transmission capabilities shown in Table 1, below. In some configurations that require long transmission distances, such as for motorsport applications, higher-powered alternative technologies (e.g., radio transmission) can be used. In other configurations, the communications system can operate with external repeaters in communication with higher-powered radios or other BLE devices. In still other configurations, a wireless sensor network (WSN) architecture can be used for connectivity to thebase station160.

  	Class 1	100	mW	100 meters (330 Ft.)

• In an exemplary embodiment, as discussed above, thedata storage module144 is configured to store physiological data on theathlete monitoring unit110. Thedata storage module144 may comprise different types of storage, such as on-board random-access-memory, microSD cards (e.g., permanently installed), and may be supplemented by storage at thebase station160, and/or storage on a remote server (e.g., the cloud). Alternatively, all data may be stored at thebase station160 and/or storage on a remote server instead of being worn by that athlete as a part ofathlete monitoring unit110. Physiological data may be stored (or synced to a base station160) in thedata storage modules144 continuously or intermittently depending on many factors, such as power capacity, range from abase station160, physiological data and respective thresholds, etc. For example, theathlete monitoring unit110 may store (record) and communicate physiological data for a duration before, during, and after an impact event (as described above). Furthermore, theathlete monitoring unit110 may be configured to store or communicate data periodically. Still further, theathlete monitoring unit110 may be configured to store (record) or communicate data according to other schemes that would be understood by persons of ordinary skill in the art.
• In an exemplary embodiment, thepower module146 of theathlete monitoring unit110 is configured to have sufficient power to support operations of theathlete monitoring unit110 for at least one full sporting event (e.g., a football game). The amount of power consumption is generally a function of the operations of theathlete monitoring unit110, such as sampling rates of thesensors122 and130 and the communications requirements (e.g., active transmission rate, “on” time, distance frombase station160, obstructions and interference, etc.). For example, during athletic events with venues (e.g., soccer, football, lacrosse, and the like), direct communication from theathlete monitoring unit110 to thebase station160 can be enabled via BLE. Table 2, below, describes typical dimensions of some exemplary athletic activities. Thus, thepower module146 ofathlete monitoring unit110 may include an on-board battery, such as a button battery or a lithium-ion battery. As a further example, for athletic events with a larger venue or field-of-play (e.g., motorsports) that require additional power, thepower module146 ofathlete monitoring unit110 may include an on-board battery and an auxiliary battery (e.g., at least one lithium-ion battery) on the athlete (e.g., in the helmet, jersey, pads, or the like) that is coupled to anintermediate communication module150, such as a repeater, for long distance communication to a base station160 (such as described above). By way of non-limiting example, such a repeater may be a Class 1 BLUETOOTH® module, or other mid-range communications module, as described above. In at least some configurations, each of the batteries are rechargeable. In some configurations, the batteries are rechargeable using an induction charging system. In still other configurations, theathlete monitoring unit110 is configured to scavenge or harvest energy, such as from the athlete, theathlete monitoring unit110, and/or the environment, to recharge batteries and/or power the device. For example, theathlete monitoring unit110 may include piezoelectric materials that generate electric voltage in response to mechanical stresses, such as by an athlete biting themouthguard120.
